  • closure at the first end and formed at the second end of the abrasive belt are preferred. Across from an arrangement within the abrasive belt can thus the entire length of the abrasive belt to be exploited. This serves that with the same sanding belt round objects with can be processed very different diameters.
  • a further embodiment according to the invention according to claim 7 provides that the Abrasive belt arranged with its first end on the drive means is and its second end is connected to a handle. Also this allows a simple change of the sanding belt realize. In addition, it is characterized in a particularly simple way and possible, the abrasive belt around the object to be machined because not even the sanding belt of his attachment points must be solved.
  • the first end of the abrasive belt is rotatably mounted on the drive means. That's it possible that when unfavorable to reach places that edited the user should not be unnatural hand and Must take arm positions.
  • the drive means is a machine insert is. This makes the grinding tool universal can be used, as well as other uses than the abrasive belt to the Machine insert can be coupled.
  • a hand-held grinding tool 1 is shown, the one Drive means 2 in the form of a vibrating head 5 has.
  • the drive of the Schwangkopfes 5 by the in FIG. 2 described means.
  • the oscillating head 5 is put in an oscillating motion. He swings around an axis 16.
  • a grinding belt 3 is guided.
  • the abrasive belt 3 has a closure 4, through which the first End 11 with the second end 12 of the abrasive belt 3 releasably to a Ring is connected.
  • the shutter 4 exemplified a Velcro 4 described.
  • the Velcro 4 is arranged so that he between the oscillating head 5 and a to be machined Subject matter lies.
  • the sanding belt 3 is about the object to be processed laid around and the Velcro 4 closed again.
  • the operator is lightning fast in the Able to start working on the object.
  • As well fast is a change of a worn abrasive belt 3 before yourself.
  • the oscillating head 5 is moved by a gear 7, which in a housing 18 of the grinding tool 1 is mounted and by a motor. 6 is driven.
  • the drive is not essential to the invention ' Lich, so waived a closer execution of these elements becomes.
  • a drive shaft 8 is formed, which rotates about a longitudinal axis A of the grinding tool 1.
  • the rotation the drive shaft 8 is arranged eccentrically by a at her Pin 9, which engages in a slotted guide 10 on the oscillating head 5, in an oscillating motion about a deflection angle D converted along the double arrow C. This happens because of that the pin 9 eccentric to the longitudinal axis A along a pin axis B is arranged.
  • the closer embodiment is shown in Fig. 2.
  • the grinding area on the object is the area that faces away from the grinding tool 1.
  • the sanding belt 3 is due to the oscillating movement of the oscillating head fifth moved back and forth over the grinding area, making it a Abrading the surface of the object in the grinding area comes.
  • FIG 3 is a third embodiment of an inventive hand-held grinding tool 1 shown. Again, here are identical, or equivalent parts with the same reference numerals.
  • the first end 11 of the sanding belt 3 is rotatable on the drive means 2 attached.
